WiFi calling does pretty much exactly what it says on the tin: You turn the function on and can then make voice calls over WiFi without having to revert to the cellular network. T-Mobile says that with the Apple update more than 90% of the smartphones on its network will support WiFi calling.

It presently has 17 million Android and Windows WiFi calling-capable devices on its network. Sievert writes that "nearly 5 million customers use Wi-Fi Calling during any given month."

Re: They have been updating WiFi calling With one-third of wifi capable device owners making wifi calls you can be sure that market is going to grow as more spots open up. It's only smart for Apple and T-Mobile to team up on this one. Deals will most certainly be put together for other providers and manufactures as well leading maybe to some really good competition in the market and lower prices?

Re: They have been updating WiFi calling Obviously haven't seen the iOS version yet but on the Android you can set the app to use WiFi as the prefered network, cellular as the prefered network, or WiFi only for calls.

The 'gleaming city on a hill,' Steve Saunders calls it. But who is going to take us from today's NFV componentry to the grand future of a self-driving network? Here's a look at the vendors hoping to make it happen.

Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
